WRENCH.

SPECIFICATION forming part of Letters Patent No. 502,870, dated August 8, 1893.

Application filed August 22, 1892- Serial No. 443,753. (No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM E. BADGER, of Quincy, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Wrenches, of which the following is a specification.

This invention has relation to wrenches generally, and has for its object the provision of improvements which will cause the Wrench to take a firmer hold upon the object to which it may be applied, and let go more readily and with greater certainty than is the case with wrenches now commonly used. Other quite important purposes are also had in view in the making of my improvements as will fully appear from the description and claims appearing hereinafter.

My invention consists in the wrench comprising the features of construction hereinafter described and claimed.

Reference is to behad to the annexed'drawings, and the letters marked thereon, forming a part of this specification, the same letters designating the same parts or features, as the case may be, in both views.

Of the drawings-Figure l is a side elevation of my improvedwrench, complete. Fig. 2 is a sectional side view, part of the handle being represented as broken 01f.

It will, perhaps, be sufficientto describe my improvements as applied to a pipe wrench, though it will appear obvious that they may be employed in connection with monkey wrenches as well.

In the drawings ct designates the handle of the wrench, the forward end of which is provided with ears bin which is pivoted the shank c of the longitudinally movable jaw d.

e designates a jaw for cooperating with the jaw d, which jaw e is pivoted in a recess f formed in the end of the handle a, and g is a spring interposed between the jaws d and e, which springoperates with a tendency to separate the jaws. Any form and arrangement of spring may be used. As herein shown a helical spring is employed, one end of which is seated in a recess formedin the upper surface of the jaw e with the other end bearing against the lower surface of the shank of the jaw d. The shank c of the jaw d is, for con venience, slotted, as at h, and the rearward end of the said shank is constructed as a nut 2', through which the adjusting screw j is tapped, as shown.

It designates a socketed nut arranged in the slot h of the shank o and provided with a hole for the reception of the pivot pin Zwhich also passes through the ears b of the handle. The inner end of the adjusting screw j is seated in the socket of the nut hand is provided with a groove m for the reception of a pin n which passes also through one side of the nut at its socketed point. With this construction it will be seen that the shank 0 will be arranged so that it may rock on the pivot pin Z, and by turning the screw j the jaw 01 may be adjusted to any desired position longitudinally of the handle and with respect to its nearness to or distance from the jaw e. By pivoting both jaws, as described, a construction is provided which permits both jaws to readily adjust themselves to the pipe or other thing acted upon so as to take the most secure hold, and the spring 9 acting upon bothpivoted jaws opens or separates the same so as to cause the same to .let go upon the instant there is a let up of exertion on the handle.

The nut 11 may be made as long as desired so as to give the thread of the screw j as long a bearing in the said nut as maybe necessary to prevent a stripping of :the thread; and said thread may be made square and as coarse as may be thought best.

Having described the natureof my invention and explained a way of constructing and using the same, I declare that what I claim is--- 1. A wrench, comprising in its construction, a handle, a jaw pivoted in the end of the handle, a rocking jaw movable longitudinally of the handle, a screw independent of the handle and arranged parallel with the same for adjusting the rocking jaw only, and a spring interposed between the two jaws beyond the pivotal point of the rocking jaw and pressing with equal force against the two jaws to separate them, as set forth.

2. A wrench comprisingwin its construction a handle and jaw pivotally connected therewith, a longitudinally movable jaw and its shank pivoted on the handle, said shank being name to this specification, in the presence of provided with a slot, a socketed nut through two subscribing witnesses, this 5th day of Au- Which thepivot pin of the shank passes, and gust, A.

In testimony whereof I have signed my WALTER S. MOLEOD.
